    Question

      A solution contains 1/ 10000 moles/I H+ ions. What is

    the concentration of hydroxyl ions in this solution?
    A 10^-10 moles/litre Correct Answer Incorrect Answer
    B 10^-4 moles/litre Correct Answer Incorrect Answer
    C 10^10 moles/litre Correct Answer Incorrect Answer
    D 10^4 moles/litre Correct Answer Incorrect Answer

    Solution

    Product of H+ and OH- concentration= (H+)   (OH-) = 10-14                                                                                    = (10-4) ×(OH-)= 10-14                                                                                     = (OH-)= 10-14/10-4= 10-10 moles/litre
